About These Units
Parsec (pc)
A parsec (pc) is an astronomical unit equal to approximately 3.26 light years or 3.086×10¹⁶ meters. Parsecs measure stellar and galactic distances using parallax. The Milky Way galaxy is about 30,000 parsecs in diameter. Kiloparsecs (kpc) and megaparsecs (Mpc) measure larger cosmic distances.
Kilometer (km)
A kilometer (km) is a metric unit of length equal to 1,000 meters or approximately 0.621 miles. Kilometers are the standard unit for measuring road distances, running races, and geographic distances in most countries worldwide. Common conversions: 1 km = 0.621 miles, 1 mile = 1.609 km.
